Which radars cover Marietta?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 61 miles east-southeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Marietta | View |
|---|---|---|---|
| KILX Lincoln, IL | 61 mi east-southeast | 4,600 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 78 mi north | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 125 mi south | 13,600 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
